I put a new tyre on my CAAD 5 (best bike). The old one had served me well but I noticed on my imperial century ride at the weekend that it had pretty much worn out. I think it could perhaps last another ride or two but it isn't worth the risk.
After that I
removed the new tyre on my CAAD 5 (best bike) - I needed to patch the tube that I had damaged when putting the tyre on!
I patched the tube and was a lot more careful refitting the new tyre. It has held pressure for hours now so it should be okay.
It means that for the first time in about a year, I have matching tyres with very little/no wear on them.
Hmm... perhaps I should now check the tyres*** on my singlespeed bike, which I will be using on a 'long' imperial century ride on Saturday. The tyres were not new when I put them on the bike and I have ridden... (checks log) ... 3,700 km (2,300 miles) on them since then!
*** PS They look ok for Saturday and another few rides but will need replacing in the summer.
